We have a datacentre instance of JIRA with Crowd as the credential service. In the past 2 weeks we have started having a problem where the last login information is not being updated.
Checking the database shows that the db is being updated (e.g. updated_date is showing today for most users) but login.lastLoginMillis is not updating since the 17th Jan. The date here is the same for all users so it looks like something happened on the 17th that is impacting the update of this field.
Has anyone seen anything like this before and have any suggestions where to look?
